Introduction to Array by R4R Team

Array is the collection of the same data type.
-It is possible to create an array of any type.

Syntax-

type array_name[size];

Integer array:

Syntax-

int array_name[size];

-Here size defines the number of element an array have.

Character array:

-String is called as character array.

Syntax-

char array_name[size];

Example-
a=[1,2,3,4,5]
printf("%d",a[0]); //1
printf("%d",a[3]); //4


program-

#include< stdio.h>
int main()
{
int a[100],i;
printf("Enter 5 numbers\n");
//take input in array
for(i=0;i< 5;i++)
{
scanf("%d",&a[i]);
}
printf("Now we have 5 numbers in array,i.e,\n");
for(i=0;i< 5;i++)
{
printf("%d ",a[i]);
}
return 0;
}

output-

Enter 5 numbers
12 18 90 4 56
Now we have 5 numbers in array
i.e,
1218 90 4 56

-In this program, we define a array by a[100], where 100 shows the maximum number that can be store in array.
-But we put only 5 numbers in array and print them.
